ctrl14

ctrl14 —
Allows a floating-point 14-bit MIDI signal scaled with a minimum and a maximum range.

Description

Allows a floating-point 14-bit MIDI signal scaled with a minimum and a maximum range.

Syntax

idest ctrl14 ichan, ictlno1, ictlno2, imin, imax [, ifn]

kdest ctrl14 ichan, ictlno1, ictlno2, kmin, kmax [, ifn]

Initialization

idest -- output signal

ichan -- MIDI channel number (1-16)

ictln1o -- most-significant byte controller number (0-127)

ictlno2 -- least-significant byte controller number (0-127)

imin -- user-defined minimum floating-point value of output

imax -- user-defined maximum floating-point value of output

ifn (optional) -- table to be read when indexing is required. Table must be normalized. Output is scaled according to imax and imin val.

Performance

kdest -- output signal

kmin -- user-defined minimum floating-point value of output

kmax -- user-defined maximum floating-point value of output

ctrl14 (i- and k-rate 14 bit MIDI control) allows a floating-point 14-bit MIDI signal scaled with a minimum and a maximum range. The minimum and maximum values can be varied at k-rate. It can use optional interpolated table indexing. It requires two MIDI controllers as input.

ctrl14 differs from midic14 because it can be included in score-oriented instruments without Csound crashes. It needs the additional parameter ichan containing the MIDI channel of the controller. MIDI channel is the same for all the controllers used in a single ctrl14 opcode.
